OpenWrt for LX2160A-CEX7 rev2.1

Hello everyone, can you tell me how to build openwrt for OpenWRT for LX2160A-CX7 rev 2.1 ClearFog? I tried to build using the standard configurator. OpenWrt Firmware Selector . But nothing is loading, trying to boot through UBoot did not help. I guess I need an OpenWRT build with the correct .dtb. I’m asking for help.
